A San Pedro fish canning and packing company that pleaded guilty to federal wildlife trafficking charges has been fined and sentenced to probation.

Tri Marine Fish Co. under-reported the weight of sardines brought to dock in 2008 and 2009 by nearly 650,000 pounds, resulting in underpayment to several local fishing vessel operators and inaccurate harvest data given to fisheries biologists.

The company pleaded guilty to two misdemeanor counts in federal court May 5.

U.S. Magistrate Judge Stephen J. Hillman ordered the company to pay a $150,000 criminal fine, including about $40,000 in restitution to the boat operators and the state Department of Fish and Game. The company also received three years of probation.

The case was investigated by the National Oceanic and Atmospheric Administration’s Office of Law Enforcement and the state Department of Fish and Game. The sentence was announced earlier this month by the Los Angeles U.S. Attorney’s Office.
